ron MACHINE.

Application led September 9, 1925, Serial No.`55,401, and in Austria .Tune 2, 1925.

This' invention 4relates to improvements in ice-machines particularly machines for man# ufacturing limited quantities, and it is the principal object of the invention to provide an ice-machine mounted in an oscillating frame suspended by means of pendulum arms. y l

Another object of the invention isthe pro# vision of an ice-machine, the water bottle and acid container of which are removably i arranged within the frame and which are connected by means of a specialconnection ending within the acid container in a glass tube having a flange so that the air removed from the water container is discharged through the acid being in a state of agitation.

A further object of the invention vis the provision of an ice-machine embodying a vacuum-pump the piston rod of which operates in a stu'iiing box which is provided with an oil seal.

A still further object of the invention is the provision of an ice-machine equipped with a pump connected with an oil-catcher embodyingl a plurality of oil dele'cting plates.

The invention furthermore includes a means for operating the ice-machine by means of a motor, the shaft of which is coupled in apeculiar manner with the shaft of a' Worm ear and crank producing the oscillation o the frame and also a transmission coupling coupling the pendulum arms by means of a slide-coupling to the operating mechanism while said arms are rotatably at- 4 tached to the frame standard.

These and other objects and advantages of my invention will become more fully known as the description'thereof proceeds and will then be more specificallyl defined in the appended claim. l

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a front elevation of the ice-machine constructed according to my invention. Fig. 2 is a top plan View thereof. I Fig. 3 is `a detail view of theJ transmission device.

Fig. 4 is a vertical section through the air pump and o'il box.

Fig. 5 is a section through the upper part of the acid bottle.

A base frame a, carries removably the two containers b and a for the reception of acid and waterA respectively. The frame a is -arms e.

The acid container b is oscillated by arm f fulcrumed at g and connected at one of its outer ends to one of the armere.

The water bottle c is preferably made in parts in order to facilitate the removal of the ice to .be made therein; and is connected to the acid container b by means of a pipe connection h. A valve 72,1 is rovided in the .connection at the knee thereo leading to the water container,'adapted to allow the admission of air after the termination of the refrigeration or ice-making process. v

The pipe It is attached at its opposite end to the knee-piece h2 of the acid container I) and the other end of the knee-piece h2 lis connected to a lass tube j within the upper part of the acicontainer.4

The glass tube enters the acid container b and extends therein to the level ot the acid. Within the neck art of the acid container the tube j has a ange 7'1 (Figo) preventing a scattering of the acid and entering of the same into the upper part ofacid container. b. y l

The flanged cover b1A of the acid container is provided with a bore in communication with a hollow stem b2 ofpipe Z leading to thev pump 7c, and a valve near the stem b2 is intended for preventing the oil collecting eventually within the lower part to come in lcontactcwith the acid.

The air pumped out of the water bottle in the ordinary well known manner in order to create a vacuum in said bottle, is led through the pipe 71 the knee-part h2 and the glasstube j into the acid container, and from the latter is guided around the'glass tube in theA direction of the arrows into the upper .part of the acid container yand from there through stem b2 into 'the' air pipe Z and through t-he same' to the pump ,7c or its cylinder. The piston of the pump has an oil seal towards the outside and the oil is contained withinthe upper part of the pump cylinder.

In order to prevent the oil from leaking Amounted to oscillate between standards d by means of the rotatably suspended pendulumthe inner Wall of the box.

charge of the pump. This oil catcher comprises a metal box m having a removable cover a and a plurality of inclined oil catching plates m1 having their ends spaced from It will be clear that the oil carried along with the pumped out air will be arrested at the plates under the action of the centrifugal force and will flow back into the oil chamber-when the pump is not working.

If an operation of the ice-machine by motor 0 is desired, the shaft p of which engages the shaft g of a worm (rear, and both shafts are coupled elastically -by means of a spring s held in position on both shafts by means of tension pins or screws, 'or the like.

The motion of shaft g is transmitted by means of a worm 1' arranged within a suitable housing engaging a Iworm wheel t to the same by suitable means of translation to lower the high number of revolutions developed by the motor shaft. A

The oscillation of the frame is produced by means of a crank u on the shaft of the worm wheel t to which a rod v is attached which engages the rod f fulcrumed-at g and l transferring the motion to the pendulum The opposite end of rod f is' guided within a slide w so that the pendulum rod e. re-

ceives an up and down motion as it is rotatably secured to the frame.

.Iiifthis manner a uniform oscillation of thel frame, favoring a quick formationof the ice', is effected.

'It will be understood that While I have shown and described as an example the preferred embodiment of my invention, the same can be subjected to many changes in its general arrangement and in the construction of the minor details thereof, without departure from the spirit of the invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

In an ice-machine of the class described comprising a plurality of standards, an oscillating frame suspended between said standards, a motor on said standards having a shaft, a worm, a shaft for said worm, and

a spring coupling motor shaft and worm shaft, a worm wheel in mesh with said worm,

a crank arm on the shaft for said worm pensating valve for compensating the vacu l um in said bottle. v
